During May 2025, contributed to the ORNL/GridKit repository by developing a new data-logging capability for the IDA simulation. This work centered on implementing a callback mechanism in C++ and CMake, allowing custom data capture at each simulation time step. The approach involved refactoring the simulation’s main execution flow to integrate the callback, which improved both data integrity and maintainability. Additionally, updated example code and documentation to guide users in adopting the new functionality. The focus on callback functions and simulation software design addressed the need for more flexible and robust data logging, enhancing the overall usability of the simulation framework.
